Recent research strengthens the conjecture that human decision-making stems from a complexinteraction of rational judgment and emotional processes. A prominent example of the impact ofemotions in economic decision-making is the effect of regret-related information feedback on biddingbehaviour in...

Auctions are nowadays a popular and frequently employed market mechanism in electronicmarkets. In economic literature, the success of electronic auctions has been largelyattributed to the reduction of transaction costs, the large number of potential buyers,and the independence of time and space....

The unmediated call auction is a useful trading mechanism to aggregate dispersedinformation. Its ability to incorporate information of a single informed insider,however, is less well understood. We analyse this question by presenting a simplecall auction game where both auction prices and limit...

Theoretically and experimentally, we generalize the analysis of acquiringa company (Samuelson and Bazerman 1985) by allowing for competition ofboth, buyers and sellers. Naivety of both is related to the idea that higherprices exclude worse qualities. While competition of naive buyers...

A vast literature shows that individuals frequently violate normative principles in reasoning. In evaluatingthe relevance of these findings for psychology, economics, and related disciplines, it is natural to askwhether reasoning errors reflect random aberrations or systematic biases. One...

The price mecanism is the primary means of information transferin decentralized economic systems. High prices indicate highdemand, whereas low prices indicate low demand. Thus prices arethe signals for accelerating or slowing production. However, usingsequential, multi-unit auctions, we show...

The results of an asset market experiment, in which 64 subjects trade two assets oneight markets in a computerized continuous double auction, indicate that objectivelyirrelevant information influences trading behavior. Moreover, positively and negativelyframed information leads to a particular...

This paper provides an overview on the simulations andexperiments we have done in order to better understandhuman-agent interaction in a market environment. We findthat the introduction of software agents does not necessarilyinduce a more efficient market. More surprisingly,information on the...

A vast literature shows that individuals frequently fail to identify the normative solutionsin logical reasoning tasks. Much attention has been devoted to the study ofthese deviations at the individual level; less effort was exerted to investigate whetherinstitutional settings might facilitate...

A great deal of late bidding has been observed on internet auctions such as ebay, which employ a second price auction with a fixed deadline. Much less late bidding has been observed on internet auctions such as those run by Amazon, which employ similar auction rules, but use an ending rule that...
